Missing documentation for nano.to usage

[kopeboy]

I remember we could customize the appearance of each page with query parameters but I can't find the docs anymore.

Some of your docs link to inexistent paths or anchors, like https://docs.nano.to/usernames in your current README here, or https://docs.nano.to/#usernames found at Docs button at https://rpc.nano.to/#known). The URLs actually respond but there's only the RPC docs, not the Nano.to docs.
